DAVID LAZAR, 0F BROOKLYN, NEW YORK! o'oin-oon'rnomnn VENDING MACHINE.

Application filed August a, 1922. Serial No. 579,387.

This invention relates to-coin controlled vending machines especially adapted for use in restricted places and has for an object the provision of a machine which mayf'b'e attached to the backs of seats in theaters,- halls and other places of like character for the purpose of vending articles such as candy and the like. r To this end, the invention aims to provide a vend ng mach ne from which all pro ecting members, such as-operating knobs,'compartinentblosures, locking devices or like ObJGCtlOIlZLblG features have been elimlnated,

so as to prevent injury to the garmentsof persons passing between the seats.

' Another objectof the invention is the provision of a coin controlled machlne from which the operating mechanism may be removed as a unit, so that a'damaged mechae nism may be removed and another substituted within a relatively short time and with a minimum amount of labor and thusavoid the necessity of repairing the machinewithin the restricted space provided between the rows'of seats, the mechanism being further constructed so that the machine must be empty to permit of the said mechanism being, replaced.

Another ob ect of the invention is the} forautomatically closprovision of means ing'the coin chute to prevent the insertion of a coin before a PlQVlOllSlY inserted coin acts to 'release the article being vended, whereby interference with the operation of the machine from this cause will be prevented. r 7

Another object of the invention is the provision of means whereby an article or a coin other than the proper operating coin, will, when inserted within the coin chute, be returned without operating the delivering mechanism. I

Another object of the invention is the provision .of a machine of the above character which includes a cover capable of being removed without disturbing the operating mechanism, whereby the latter may be conveniently inspected. 7

:A further object of the invention is the provision of a vendingmachine which may be locked only by means of a special key,

so that annoyance oocasionedby empty'machines, or those filled'with paper or. other foreign articles may be avoided, enabling the attendant to determine at a glance the machines needing refilling.

the support 20 by ith the above and other objects in view,

the invention further includes the following novel features and details of construction, tobe hereinafter more fully described,illustrated in the accompanying drawings and pointed out in the appended claim.

tached. The invention includes an attaching frame 21,- which is -substantia1ly,,rec tangular'in shape and which is secured to means of screws 22 and spacing sleeves 23, so that the face .24v of t e attaching frame will be spaced from the 2 support 20. This frame has removably secured thereto what will be hereinafter referred to as a mechanism unit, indicated in its entirety by the reference character 25,1.

the said unit carrying all of. the operating quickly removed and 'a new mechanism subin the frame 21, serves to hold the mecha= place of amusement.

nism unitflfi i n placep By ren'ioving the screw ZO the unit may be quickly detached and another substituted, so that any -n1achines out oitiordeix may be conveniently restored within the" limited time provided between performances in a theater or other The article compartments 53? areas pre viously statcdyspaced apart and are provided with longitudinally disposed slots 3:?

tin theirouteravalls andat their tops with removable covers or closures 233, the latter being slidablethrongh slots 351: provided in the plate 26 and when in open position, these coversorclosures willoccupy a space atthe.

rear of the plate so as to leave anneobstructed opentop for the ejection. t of a vended article, (not shown). The npper edge of the slot 34; is ofiset as shown at 35 so as to facilitate the passage of the closure 33 therethrough andperlnit the same to fall behind the plate 26; where; its downward movement will be limitedby means of a stop 36, springs tli" attached to the closure 33 servingto force the latter downwardm One edge of the closure is provided with a lip 38avhichengagcs the lower edge of the slot 3 1 when theclosurc is in open positioin while extendingd'roni the top of the closure near the UIJPQSltG QdgG thereof is a llange 2:39 which engageslhe stop 36.

"lhe elosnrestl3-are heldin closed posit on by means of a loclm'i'g spring 40, the latter being provided withn log all which engages beneath the rear edge ofithe closure 33.

This locking spring secured to the rear taceof tlie plate 26 asshown at 4-2 and opcrating-beneath the Upper free end oi the sprin a rocket-flair lii whoexe opposife ends are moniitrd in bearing legal-t. The

bar lti is provided with alnpg lfnwhirln when said baris rocked, is adapted iocengngeitl s iiring ltl to release the lllf y meet with the "closure '33 and i pernii J latter to open under the intlnenceot the spring 37. i

lihttendin l'roln each oi the rocker bars i b n is 'alirarin 46 which immi ant an oii'- "setportion i7 of-a vertically lllOlftlblelOCl whichis slidable i'nbeai'ing lugs 49 carriedjhythe pIateQG: The lowenends of the i1. rods 8bear iipon tlieedges of-"spaced cams 50 which are rotatable upon a, shaft 51 and iofthe coin chute 59'.

i i l WlllCll are yieldingly forced downward upon these cams by means of a spring 52, the latter also scrvmg to resist pivotal movement of the rocker bai t3 and consequently resisting upward movement of the rods 4.8. Adjacent each of the rocker arms ltl is a spring actuated triggerhfl, which is adapted to en gage lugs 5 .1 so as to prevent engagement of the leg 45 with the spring 40, these trig-- gers being provided with key engaging portions which are adaptcd to be engaged by a key 56. ally operating the key 56, the triggel's53 may be moved against the action of spring 57 so as to release them from beneath the leg 54: and permit the rocker bars:

43 to release the springs -10, whereupon the latter wlllenjgage beneath the rear ends of thej closures 33 so as to hold thelatter in closed'posiftionj. ()rdinarily, gin nnichineso't this character, the [)fltilitlgfi is ntilized to lock the article compartments in clot-red; position and unauthorized persons maythen insert an empty package, or may stuff the con'lljnirt-nient with paper so as to locl'i the san'ie and an attendant is thus unable to determine which of the i'nachines need re lilling. v "lhis objection is obviated gin the present: machine by the requirement ot a special key for locking the article conipaitmeat. n i a a H a r Each con'ipartnient is inrovided in its toe tOll'l with a spring actuated ejector ii ieniber 58, having a spring 59 positioned between a said member and the bottom ,of the compare incnt: 32,

so that when the closure is released, the member 58 Will be actuated to eject the article A.

Located between the c linpartnients32 is .a coin chute fiffavlnich is adapted tore live a a C0111 of suitable denomination, tor example a nickel. This coin passes downward through the chute and engages :rstationary stop (it) and a movable stop til, the "said stops being nornnllly spaced :1 distahce less than the diameter of a nickel. Tithe niirkel is released by means of aplungcr 2 which operates in a Lgnide block 63 secured between 32 and to themiterwall l n downward movement, the coin passes aspring actuated coin ejecting doc; (34; which rests above the the con'ipartmeats upper edgeot the coin when the latter engages the ate 1 (l and ti] and when theplnnger is depressed in a manner hereinatti'er cxiiilained, the stop 61 will be move to Ire lease the coin. lVhen thns reht the coin. willldrop upon the ripper edgexol a pivotally mounted rocker arnrtitj, 1C1) is pivotcdmto the i plate 26 ,at 66 and ,which is providedfwith a longitudinal flan e GTalong its upper edge, the downward inoven ient of thei plunger 62 also serving to operate the rocker arm 65 to cli rect the coin into a coin receptacle 69 located at one corne xof the plate 26, Due to the n rmally" incl H d.

either of the studs 28 so as to provide a fulcrum for the key and the letter is inserted through a slot provided in the side of the cover 71 so as to engage beneath the closure 33 and lift the some against the action of the spring" 37. Due to the oll'set edge of the slot 3-1;, the elosurewill he guided horizontally over the upper end of the compartment.

In Figure 11 there is illustrated a moditied form of closure which is hingedly mountreserved to make such changes as properly fall within the scope of the .uppended eluim. I-Izwing described the invention what is claimed is A coin controlled vending. machine embodying article compartments, closures for said compartments, means consisting oi": spring arms operutively associated iuiith said closures to retain them in closed positions roelmhle members having devices engngeuhle with said spring arms to release said closures,

resilient meunsnnder tension for actuating the closures when released, coin controlled means embodying longitudinally movable rods operutively associated with the rockable unemhers, and coins operzitively dissoeiuted in connection With-the longitudinolly movable rods, wherebythe rockiible members may independently and alternately operate to alternately open the article compartments. In testimony whereof I affix my signature.
